Wait...I don't get what you've agreed upon. Yes I changed ~NSIS\Source\exehead\config.h (uncommented #define NSIS_CONFIG_LOG). Now I gather that I recompile this source code.
Could you tell me exactly how to do that; where is the workspace, the .dsw, that I need to recompile. Or maybe I'm wrong on this and if so, can you re-steer me?
